"The Valley" -- the San Fernando Valley that encompasses the northern portion of the City of Los Angeles (although it constantly wants to secede). Known for Valley Girls ("yeah, like gag me with a spoon... as if!"), the Galleria and a climate significantly hotter than the other side of the hill and thus rivaling Hell. Also the porn capital of the Western Hemisphere.
"My girlfriend is a figure model in the 818. So no future, but at least the sex is good."

818 - (n) An area code in the San Fernando Valley ("the Valley") area of the Los Angeles, north of the Santa Monica Mountains.

The area code was featured, in a somewhat derogatory manner, in the movies Go and Swingers.

People (likely due to its use in Go), will sometimes use it to refer to someone going apeshit.

Chinese internet slang.
Similar to how, due to the sound of the pronunciation in Mandarin 666 is slang for "Awesome" or "Super smooth" (six, and smooth sounding pretty much identical in the language) 818 is a slang term for 2 people who are close to each other, usually implying a romantic connotation. (Usually online)
For example:
Heard that there's some sparks flying between those two. Have you heard if they've made progress? Give me the gossip on their 818.
